I never saw the other one, but it was described to me a few years ago by the son of the builders after the house was sold and security no longer an issue. He said his father was concerned about nuclear war, and that he was also worried that the house would burn down as a result of the blast. His solution was to have an underground blast shelter built outside the house, with a corridor entrance from the basement and another exit in case the house burned/collapsed. Yes, this was a very high budget bunker.

After 9/11, my dad filled a duffel bag with some energy bars, a couple gallons of water, some penicillin, and a map. Amid scaremongering headlines about imminent anthrax and “dirty bomb” attacks in the city, he wanted to have some supplies on hand in case we needed to get out of Brooklyn fast. Were he to assemble such a bag today, he’d likely stumble on a number of companies promising a more wholesale brand of disaster preparedness: a box full of shelf-stable freeze-dried meals, to be revived from their dessicated state with the addition of boiled water.
